Re: Tc default value in GTS

Good question. The only other information I have is from the QoS Exam Guide,
p355:

"The Tc value defaults to 125 ms, but interestingly, GTS can use different
default Tc values, based on the configuration settings you use."

Perhaps someone else can shed some light on the reason...
